You can set the assist levels as you like, because they will never go above 18A if this is your set limit. Do you think this is sufficient for my needs as listed above? BBSHD Voltage Problem Firmware Update & Instructions This is the newest and most updated Bafang display. 3 Insert the programing cable (USB-Serial Adaptor) into the computers USB port, and install whatever software it requires. I just bought it one week ago and battery show me wrong percentage on the screen. The Bafang programming feature is ONLY for the Bafang mid-drive motors. zie wel de voltage maar niet het bereik de RANGE is dit een fout of hoort dit zo My best guess is that changing those settings cant harm your motor/controller, otherwise the controller would limit those settings anyway. Thanks! If you set this to a higher value, your bike will have more power. Older versions might still have the 30A controller. Hitting the magnifying glass will automatically select the correct port. With 12-14Ah, you could have some range anxiety ;p. The BBS02 750W will have more than enough power for you needs, the BBSHD definitely isnt necessary. Im having trouble getting started. I would recommend reinstalling the drivers or trying to install another driver that you can find on the internet. de andere motoren doen die dat wel zoals de BBSHD. Ich hoffe, Sie finden etwas heraus, das fr Sie funktioniert. I am not responsible for any damage that might occur. I recommend 36, since this is the default and in my opinion, works perfectly. Or is there anything I can do in the programme so I can keep up with my bike? All other settings should work fine with a 48V battery. If this happens, the motor is cut-off. So if you do this, the chance that something will fail increases. If not: do you know a way to change the settings of the M420? Only the Bafang BBSxx series can be reprogrammed. If everything works you can try inserting custom settings again and see if it will work this time. The problem with this is that you cant pedal along in low gears since the cadence of your own pedaling would need to be really high. I intended to use this on a touring bike. Will do soon and let you know. If you want to ride on private property you just change the speed limit on the display. Ok thats what i thought. No problem, you can ask me anything. 1) You can take the 48V file, the only thing that you would have to change is the low battery protection. It only does this when you are pedaling at a high rate (so if you have reached a constant speed). The software cant adjust gear ratios unfortunately. Error code 30 could also be caused by a faulty controller or display. The RPM at which the motor will operate at maximum efficiency is, in fact, way higher than the cadence (RPM) at which your own leg power will have the best efficiency. It is effectively the thing you would do when using the throttle, the motor will do all the work. So even if the sequence was wrong nothing bad should happen. I am a strong cyclist and I find the assist levels to be too strong for the most part. Do you mean setting it to speed gives you a more controlled range on the throttle? In your reply to me you stated that their is another controller for the M400 that will accept throttle. Can you direct me to this controller, I do have a tech that says he can program the controller for me. stc-isp6.86.rar I, however, do not recommend setting this to 25. To start viewing messages, select the forum that you want to visit from the selection below. Its stops only when i use the brakes to stop the motor. And can you tell me what the current battery voltage it, when it states 50%? So if you are not planning to ever use the Bafang BBSHD 1000+ watt power, I should buy a less powerful cheaper motor. I hope you figure out another way of fixing it. I recommend current since this is easier to calculate by your controller. The display you have indeed has two modes: standard and sport. First: You accept all responsibility for performing any or all of the steps below, and if your stuff explodes in a supernova, or simply fails to ever work again, sorry about that, I cant help you there. You can simply use the suggested settings in this guide. Helpful getting started, but the download is missing some files. In general: yes, you can use a 52V battery with an 48v controller/motor. support Ready to program!!!! i know this is a bit of a different question, but do you think it is possible to set the controller to 25km/h on startup every time when it is started? Hi Dima, I am having the same problem. Any other settings for this ports configuration. https://drive.google.com/file/d/1rerH9mTJQfyJcuiB5atlN_aV99v8UBij/view Otherwise it will not work. If I know these numbers, I will be able to tell you if gearing/small wheel size is your issue. Assist 4 80 / 100 Assist 2 40 / 100 BBSHD unpotted Display Power Line.jpg README.md STC15W4K32S4-en.pdf README.md Bafang_BBS02_BBSHB Its my first ebike, i rode more than 2000 km since April, but last time I every day rode 500 m abt 20% uphill on level 6 on the throttle on 34 cog, maybe this is the reason. So i ventured into the programming today. BTW, instead of unplugging and replugging the battery, I turn it off then on. Apart from that, I wouldnt know what could cause the issue. This is what you would expect. ONLY CONTINUE IF YOU ACCEPT THE CONSEQUENCES OF YOUR ACTIONS! I have never heard of this issue before. It rode ok on pavement, but was worthless on dirt trails. If you want the pedal-assist to start the fastest when you just pedal a small bit, change it to 2. The little magnifying glass does not offer me other COM. It has just been installed. My battery range is 100Km, normaly i use 1/5 2/5 PASS . Some controllers can handle this better than others. Regards, Thanks in advance brother. I did some tests. This setting doesnt imply that the maximum speed with the throttle is 40km/u. It could just be normal behaviour (due to less full battery), but thats hard to tell from here. I tried adjusting the resolution, but that didnt help. You could increase the slow start number in the throttle tab. Can I still set the Speed Limit to 100 without straining the controller? If you hold down the + symbol it will switch back and forth from these modes. You can find instructions on how to do this here: (Another tip is to go in the programming software and see if the low battery protection is set at 41. Max current: 28A, If 28A is written on the controller, this will be the maximum. You should check all physical connections first. Now click File in the left top corner of the program. Thanks for your reply. The setting on the display will set this setting and the pedal-assist setting at the same time. So there indeed doesnt seem to be anything wrong with your battery. I do not have the MAX PAS setting in the display. This setting will decide after what number of steps the motor will start assisting. But getting the exact same settings on there as the old controller is definitely something that you should try first. What do you mean exactly? I am talking about these extreme situation. So if you find it convenient to have a mode in which only the throttle will really work, you can set this to 1. If thats the case, there probably is something wrong with your display. This way the battery cant be discharged further. I will look into this. Good luck reprogramming your Bafang system! Thanks Giel, I agree as do many that the Bafang Another thing Id like to ask you about is wheel size. When you are standing still, the voltage will not drop, because the battery then isnt loaded. Apart from that, I dont see any obvious problems. Check all the connections and make sure they are connected properly. A custom configuration tool is provided since BafangConfigTool is not compatible due to a different set of supported parameters. The battery percentage is based on the battery voltage. Since day 1, when using PAS, intermittently my chain wheel loses all tension causing the crank to spin about 180 degrees before the tension comes back. A programming fix is finally available to address this oversight. Interesting now even the battery percent is pretty accurate even though I normally have the display set to volts. GitHub - danielnilsson9/bbs-fw: Open source firmware for multiple Ciao Jim, I would suggest reading about the error online and trying all the mentioned possible fixes. If Bafang would fix this, it would be an absolutely near perfect motor. Using This Software Can Void Your Warranty! Can you do any damage by setting amp levels low? I would be retrofitting this to a legit mountain bike one of my bikes is a hard tail with a legit front fork, legit hydraulic disc brakes and 1 x 10 shimano drivetrain.

Would it work if I changed the speed limit of the secend tab(Pedal Assist) to 40 Km/h ?? You could also try a completely different computer/laptop. Which display model do you have? Please The video link is https://www.youtube.com/watch?v=WNmvj9PiZ08. The DPC18 display you have, is the only display that does it in this way, which is rather strange indeed. This way the motor and myself will work together. I think this probably be the correct sequence The Bafang firmware is just so that it doesnt activate the throttle in pedal assist 0. It is safer to have it at 0% in PAS 0 on start up. First of all thanks so much in advance for your replay and apologies because probably my question is not related directly with the topic. I still like to pedal . I think that it doesnt have to do with the controller but I could be wrong. Did the controller fail right after the usb procedure? Wenn das Programmierkabel nicht zu Ihrem Anschluss passt, wrde ich nicht versuchen, die Pinbelegung zu ndern. This is a problem that often occurs on the highest gear. You cant just lower the current and get the same power, this is physically impossible. So speed is not my priority. Its a shame that controller failures are rather common with the Bafang mid-drive motors. Like are all wires connected properly. Hi Giel. There unfortunately is no way to increase the time that the gear sensor deactivates power. I would then first try to contact the seller, they might sent in a replacement for free if you can indicate that all other possible fixes didnt show any result. I indeed would try a new cable first. The lower this setting, the faster the drive unit will decrease power as you pedal faster. The max current for the Bafang Ultra is 30A. . So I would just say to pedal in the gear in which you can put in your own leg power the most comfortably. You probably wont be able to change the top speed at all. I dont know what the programming cable itself looks like at the BBSHD end, presumably the same as the Display cable. Assist 4 -current limit 60 speed limit 90. I have now changed the link, it should work now. Yes, I reprogrammed my trekking bike (Fischer ETH1861) with the software. Setting the speed limit in the display is however way easier than doing calculation with RPM. Therefore no pedal power is transferred to the bike. 9/100/100. I will respond to you within 24 hours. I have a Bafang 750W BBS02 with 48V 17Ah battery. You dont always get this notification though, so that can cause compability problems.

If you set the current limit to 10% in assist 1, but speed limit to 100%, it simply wont have the power available to actually hit max RPM. (If youre not sure which one it is, it shouldnt hurt to try any of the ones it lists until one of them works) Do you think that flashing my controller with a 48v controller will solve the problem? John. But the difference is that the entire firmware needs to be reflashed. The reviews on the 104 BCD chainring adaptor seem luke warm as many reviewers say it pushes the chain ring out from the Bottom Bracket too much and thus making the chainline to the largest cog at the back (46T) really off. If you want to maximize the range, you indeed should set the lowest possible amps, that still gives you sufficient assistance. Most of the time you will have to press some button combination so that you will enter a special menu on your display. the issue is now fixed and I have been able to reset all the values and save on my PC.
